Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning assistance data is provided for multiple regions separately, then positioning accuracy is improved, but processing power consumption increases
Solution Approach 1:
The patent segments positioning assistance data by associating different data sets with specific geographic areas. The UE receives multiple positioning assistance data sets, each tagged with area information, and selectively processes only the data relevant to its current location. This segmentation allows accurate positioning without processing all available data, thereby reducing power consumption while maintaining positioning precision.
2Measurement precision
If positioning assistance data is provided for multiple regions separately, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal area association mechanism that can be applied across different positioning scenarios and regions. The positioning assistance data structure includes standardized area identification elements that work consistently regardless of the specific geographic region or positioning method, simplifying the management complexity while enabling multi-region support for accurate positioning.
3Measurement precision
If positioning assistance data is transmitted frequently to maintain accuracy, then positioning accuracy is improved, but positioning latency increases
Solution Approach 1:
The patent prepares positioning assistance data in advance with area associations, so that when the UE needs positioning, the relevant data is already available and identified. The network pre-configures multiple positioning assistance data sets with their corresponding area information, eliminating the need for frequent real-time data transmissions and reducing positioning latency while maintaining accuracy.
